League of Legends on a Mac crashes literally every game [CRASH]

Voltron032··27 votes·21,758 views

I play league on my 13' macbook pro. I play with my two roommates, one of them is a pc user and one of them is a mac user (has the same exact computer I do). Unfortunately every single game I play at one point or another, usually within the first ten minutes, my game freezes entirely and the only way to make this stop is to turn off my laptop and attempt to reconnect. Then this process repeats itself and I DC all game long. Since my buddies are in the same game I am, I know that this is not a connection issue, and my friends Mac plays perfectly the whole game. Knowing this I completely reset my computer to factory settings, updated it to the most current state it can be in, reinstalled League, and attempted to play again. I played one game flawlessly and that was awesome because this is the first time this has happened in weeks. However the very next game my game froze. My computer works perfectly for everything but this game so I am left to believe that it is a problem with League itself. This has been extremely frustrating and I would love if anyone from riot or the league community could suggest a way to fix this problem, or at least inform me my only solution is to wait for a Mac update. I have searched the boards and found that patch 4.17 messed with a lot of people's macs, but mine has only been messed up since patch 4.21.

Is anyone else having these problems and is there a solution?

Thank you

What does all this mean?

I am on a mac also and I am having the same problems. Its gotten even worse the last couple of hours.

Having the exact same problem. Every time i reconnect it crashes and I get the bug splat error.

last game I was playing with 4 friends and 2 of us had Macs (different IPs, different locations) and the two of us with Macs got DC'd and we couldn't even log in, or restart client.

Voltron0321 votes

It's infinitely frustrating to have your buddies play normally while your team suffers because you're using a Mac. This really is getting to the point this is unacceptable from riot. At the very least I would like them to acknowledge this problem on the launch screen.

I've been playing on a Mac since the days of the unsupported client, and this is the very first time I have had this issue. Played three games just fine this afternoon, then last game it freezes out of nowhere and I couldn't Command Tab out. Didn't fully shutdown, and message came up saying client crashed. Rejoined game, crashed like 20 seconds later. Not sure if this is a result of the latest update, but again this is my first time experiencing this particular issue.

FriedChickenKing2 votes

This happened to me too. So the screen was freezed and i can tell it's not because of my internet. I experienced some DCs because of internet and it just instantly close the game and shows a reconnect on the cilent. But this time, after it's crashed i can still make it into the game and keep playing. But if i want to do something like speak in chat, or use a skill, the screen is just gonna freeze again and then dc. This wasn't happening in the last patch so. And I really wish i don't get a report for this. Sorry to my teammates.item 3070 i tried my best to reconnect.

FriedChickenKing2 votes

BTW i could get out from the freeze by simply command+tab. But it concludes to a game crash. And the game will keep on crashing again and again.

Daft Josh2 votes

This happened to me as well. Was playing just fine for the past few hours (with the exception of ten minutes ago). Was in a game when my screen completely froze. I was on a Skype with a friend and he said he didn't dc. I think this is specific to the Mac clients only. I can't even open my client right now.

I played one game this morning right before the update with the new blood moon skins etc. and I could play just fine. Now, in the evening after the new patch with the new skins I am unable to play do to constant crashing of the LOL game on my mac. Idk if this is just mac related however, I am currently unable to play league of legends due to this bug.

fEARtHEgOOCH2 votes

Now my Client starts up every time, but I cannot login to the server (Did not receive response x3)... In the middle of typing this message, finally connected. Hopefully game will play through.

fEARtHEgOOCH1 votes

25 minutes into next game (24 min 58 seconds), game freezes. Joined back up when game was 50+ minutes in, and team held their own for the most part. Still ended up losing second in a row, entirely due to this bug... Both times we were up 5-10 kills 20 minutes in, with bottom lane winning hard. Will wait until tomorrow to try playing again, hopefully it is only something with the update.

I am having the same problem as well.

That Lemur Guy2 votes

So, I am getting all the same errors, but when I restart my computer it works temporarily then boots me again. Would be nice to know if riot could at least respond and let us know that they are trying to do something...

VelliStar2 votes

this happened to me as well, and i was in a game. my team won the match, and it shows up in my match history as a leave and i actually lost LP. i don't know who to go to to resolve that. it was undeserving for me to have that leave and loss of LP for a error on the clients part.

edit: i also play on a macbook, it happened 445 am on NA. east coast.

Protip: Include your OSX version number when submitting a bug report. I have a strong suspicion this is somehow related to Yosemite.

i dont have yosemite. still on 10.7

fEARtHEgOOCH1 votes

Was able to rejoin game massively under leveled/farmed. I had to constantly try and open LoL while clicking to terminate pre existing client. Once it started loading client, I clicked Launch... This of course failed, so I did the process allover again. It worked the second time, but I really hope this issue doesn't come up in my next game.

SKT TM1 Faker1 votes

Same problem. Get into a game, client freezes completely, I cannot even command-tab out. Using Macbook Pro 15", Yosemite. I have to force quit and restart, still crashes.

Voltron0321 votes

Thanks for the feedback everyone. It's good to know I'm not the only one having this problem. I played last night on my buddies Mac mentioned in the original post and his computer crashed as well while the pc was doing fine. I'm not sure how to check what version of software I have, I just know that it's definitely Yosemite and there's nothing for me to update when I check for updates via the App Store. Im not super tech savvy so I'm not sure how to look into this any further to figure out the exact version this is. The only thing that changed though when I played on my friends computer was changing the settings to turn quick cast on with range indicators. Seems far fetched to think this could be the cause of the crash but besides a different account being logged in, that was the only difference between the game working flawlessly and crashing every match. He is playing on his own account now with his own settings applied on his Mac and it hasn't crashed yet. Riot your Mac community is huge and would love to know if progress is being made to correct this issue!

Hey Voltrono32 I have some questions about your issues if you do not mind me asking. Are you crashing in game? Or are you just disconnecting from the server and lagging ping wise? If its a client issue your best bet is to download a FULL uninstaller off the app store which is free. And COMPLETELY remove league all together. Then start a fresh reinstall make sure nothing else is updating on your computer and nothing else is ruining. Make sure your computers sleep settings are off as this can activate "app nap" which can stop the install, and leave it for a couple hours or how ever long it usually takes to download(and yes you can dim the screen to black so its not burning up the screen for no reason). I also advise you to type in spotlight "disk utility". When it opens click on "Macintosh HD" and then the sub category of the Hard drive usually says Macintosh HD again unless you have multiple partitions then you need to chose the one that has league installed in it. You are going to want to in the first aid tab "verify disk and then repair disk". Then you are going to want to "verify permissions and also repair these too". Essentially this is like tuning and cleaning/fixing a car but software wise. After your done with both process which could take awhile in the box of txt you should get a final line or a green one saying Everything appears to be OK and Repair complete. Essentially what this is doing is making sure all the hierarchy of folders and their allotted permissions are matched up and are pathing correctly also it will find and fix or try to at least repair files that are possibly "corrupt". If for some reason it cant complete a repair you need to call apple asap and take it in to get an assessment as their could be a more detrimental problem with you hard drive/system. Now if it is a network issue and or connection to the server their are some personal things I need to know like for instance are you on a college campus wifi (they block certain ports). What is your ISP or internet service provider, what download and up load speeds do you have? you can find out what ISP you have and your speeds at (http://www.pingtest.net/ . If you have your own personal internet connection with your buddies knowing what ISP you have can help me figure out your IP which you can also find out under "network preferences" click on your connection and under the advance section under the second tab you should see down the page router:IP . We can use this to get into your router an manually forward the ports needed for league to help a better over all connection to the server. If any one else on your network plays as well which I believe you stated previously you will have to set up the ports as well for each of their personal IP address as well as your. To learn how to port forward go to https://support.riotgames.com/hc/en-us/articles/201752664-Troubleshooting-Connection-Issues#wq7 and find the port forwarding tab. You can also try the other possible fixes on the page as it could help as well. Also you can use "network utility" and send a packet of 10 pings to 216.52.241.254 under the ping tab. If your ping is very inconsistent or is above 100ms for more than half the pings or you experience more than 3 packets lost I highly recommend you create a support ticket at the riot support website describing in exact detail the nature of your problem. Follow these instructions from each link and include the logs attached to your ticket to riot support as these will HELP GREATLY get to the bottom of the problem quicker.

  1. The first bit of information they need is called a "System Report":
  1. Next, r3d logs in games where the issue occurred (You only need the Game logs, NOT the Air, Maestro, or Patching logs):
  1. A Network Analysis:
  1. A Process List:

In all honesty you should submit a ticket and include all the logs it asks for in the 4 steps above. Do not get discouraged my fellow summoner! Help is only a couple clicks away! Good luck! -A fellow Summoner

Thank you for the feedback, I'll get to work trying these solutions to see if anything changes. However I think I found the problem! My friend who uses a Mac, mentioned earlier in my post, actually doesn't have the latest version of Yosemite updated on his computer and its working flawlessly for him. Everyone else who is having this problem is saying their computer is updated fully as well. So if you have a Mac and wanna play league, dont update the OS! Unfortunately I already updated it so I can't play league till something with riot or apple changes... But if anyone from riot sees this, I'm pretty sure the problem is just a change that Apple made with the last update. Would love to see a fix for this soon. My league skills are slowly deteriorating.

So, I have decide gg riot you win. you refuse to acknowledge or do anything about problems when they arise. Your refusal to support your players has ended the fun of this game. You would think a company that makes the money you do would do something so support your game. I am done fighting through server lag because your servers are garbage in NA. I am don't fighting through client error because you refuse to fix them. GG riot you win. I am done.

Quantum Bread1 votes

@Have some Lemur Describe to me exactly what issue you are having? Is the the game client it's self or an internet related problem? Ie: Lag disconnects etc. I may not be riot but I am studying IT in college, so maybe my 2 cents worth of knowledge could offer some helpful advice. Yes their server/server maintenance is rather poor but there are things you can do on your end to optimize your connection and all. Stay positive my friend i just was helped via ticket submission rather quickly and I'm in the process of getting my issues all sorted out i suggest you do the same and don't be so quick to jump ship my fellow summoner! Expect the worst, hope for the best and anything in between is gold my friend ;D. Stay POSITIVE!

I'm so glad I found this thread! My Mac which runs Yosemite 10.10 is doing the exact same thing. Some games run perfectly, but 98% of my games crash about 20 minutes into the match. I've done everything suggested to fix this problem on the Support page. I've been suffering with this for months now, and It is the most aggravating thing ever. I hope there is a resolution to this issue. If anyone has an answer please let me know! I'm desperate to get back on the rift!

PumaSLAYERBoy941 votes

Have they resolve this problem? or something we can do?, I´m new to LoL, I have been playing coop against bots, and it works kinda normal, but today I just started to play PvP and happened this problem, I found here that everyone or almost everyone using mac, have this issue.

So after 3 months this post was written, is there something Riot has done to solve the problem?

Thank you

I got my mac when it was an El Captian > Yosemite (had NO ISSUES whatsoever) > Sierra (disconnects every single game) > HighSierra (No change whatsoever). Idk, I think Riot is like saying "PC MASTER RACE"

ChisatoShirasagi1 votes

My problem isn't as severe as yours, but it's still annoying. Basically once every few games, League just randomly crashes on my iMac and I'm left with a bugsplat. This is frustrating because it happens pretty early in the game where good cs and lane dominance means everything for a mid laner. I'm just glad it hasn't crashed in the middle of a fight yet...
